我最近嘗試使用 tsdx 創建一個 react typescript 組件進行編譯，但在除錯時遇到了一些問題。該軟體包已發布，并且似乎正在發布和安裝而沒有錯誤。然而，當談到實際使用時，我總是遇到：
TypeError: Cannot read properties of null (reading 'useEffect').
我有同樣的問題，useContext所以簡單地替換了功能，但現在錯誤已遷移到useEffect.
這個包在本地運行完全正常，如果我洗掉所有代碼并將其手動注入應用程式，它可以毫無問題地運行。最初我只是在解構useEffect鉤子，react但即使顯式匯入reactasimport React from 'react'; react仍然很明顯null......
查看.cjs檔案我可以看到 React 被匯入：
var React = _interopDefault(require('react'));
但問題仍然存在。
感謝任何和所有幫助，如果有幫助，將從我的 package.json 中粘貼一些資訊:)

編輯：另外，如果值得注意 - 這個專案沒有初始化為 tsdx 專案，我在切換之前遇到打包問題后，將 tsdx 構建腳本和一些元素添加到 tsconfig 和package.json
uj5u.com熱心網友回復：
只需為遇到此問題的任何其他人留個便條，在我的包中，我的常規dependencies物件中有“反應”和許多其他依賴項，package.json當我將這些移至devDependencies.
